In some embodiments, a feedback circuit is used to inject a charge into the sense electrode to at least partially cancel the parasitic capacitance between the sense electrode and the counter electrode. In some embodiments, bootstrapping of a signal from the amplifier output or from the sense electrode is used to inject a charge on the counter electrode to substantially cancel the parasitic capacitance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low noise amplifiers with feedback for nanopore applications","description":"Disclosed herein are devices, systems, and methods that can improve the SNR of nanopore measurements by mitigating the effect of parasitic capacitance between the sense electrode and the counter elect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11946894","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
